After laying their daughter to rest in a private funeral for family and close friends Thursday afternoon, Christina Grimmie’s family greeted thousands of mourners at a public memorial one day later in New Jersey.

The singer’s parents, Bud and Tina, along with her older brother Marcus, welcomed friends and fans at the Fellowship Alliance Chapel in Medford, New Jersey, for the event, which was livestreamed. Grimmie’s mother was seen giving long hugs to well-wishers. An estimated 2,000 people showed up to the memorial.

“She was a wonderful role model. I loved the fact that she didn’t hide her faith and that she showed my children that they can be a singer, they can do whatever they want, as long as they keep their faith and their belief in God,” Cherie Kulik, who met Grimmie through church, told PEOPLE at the memorial. “My heart breaks for Buddy and Tina. I want to be here to support them.”

Aaron Lodato, who first met Marcus at a Bible study held at the Grimmie home, told PEOPLE he was in shock when he first heard of the star’s passing. “I didn’t believe it,” he said. “It doesn’t feel like it would happen to you, to someone you knew. It’s one of those things where it’s something you never get over. [Marcus] and their family, they rely on the Lord.”

“She was just as you would imagine her to be. Sweet, approachable, introverted and shy but always enthusiastically receiving people,” Julie Durdin, Grimmie’s high school youth group leader, told PEOPLE. “In our small group, she was just one of the girls.”

Photos of the former Voice contestant were displayed along the dais at the front of the church while her music played in the background.

A video commemorating the singer was also released on her official YouTube account on Friday. “Christina Grimmie was taken from all of us far too soon, but the impact she had on this world in the short 22 years of her life will carry on forever,” reads the description.

The touching tribute includes footage from Grimmie’s early days as a YouTube star and her journey on The Voice, as well as emotional clips of her sharing bear hugs with her mom and brother.

The star – whom her close friend and fellow Voice contestant Bria Kelly told PEOPLE had “the biggest heart” with her fans – is also seen in the video excitedly meeting her fans and signing autographs.

The talented young star was only 22 when she was fatally shot a week ago by a deranged fan – who was immediately tackled by Grimmie’s brother – after her performance at Orlando’s Plaza Live venue.

“I thought it was incredible. To tackle a guy that did that harm to your sister, instinct must’ve taken over,” Jason Rodriguez, a friend of Grimmie’s father, told PEOPLE. “Marcus saved a lot of lives. He’s a hero but it came at a high price.”
